On front view, the Compute Module is correctly labled as 90mm X 100mm however it is not shown in the proper size on the front. the compute module should be shown with the correct proportions. It needs to take up more space. Redo and show front view
I’ll update Version 5.0 front-view visuals only so the Compute Module is drawn with correct 90 mm × 100 mm proportions and occupies the appropriate larger area. Version 4.0 stays locked.
Search started for the COM-HPC Mini type carrier-board connector needed for Tiny Tim Version 4.0 implementation.
No schematic, layout, image geometry, connector placement, or board dimensions were changed during this search.
Key Standard-Level Finding
Public COM-HPC Mini references indicate that COM-HPC Mini uses one 400-pin high-speed board-to-board connector. Larger COM-HPC Client/Server designs use two 400-pin connectors, but Mini uses a single connector.
Carrier-board side = male carrier plug / header.
Module side = female module receptacle.
The carrier plug determines the module-to-carrier stack height, typically 5 mm or 10 mm.

Flux Library Status
Exact COM-HPC Mini / COM-HPC 400-pin carrier connector parts were not found in the Flux library during this pass.
Re-check after user request to import/create the connector: Samtec ASP-230336-03 is still not available as a usable Flux library part. Public web sources expose Samtec PDF print / footprint PDF / PADS resources, but no directly importable KiCad .kicad_sym + .kicad_mod, Altium .SchLib + .PcbLib, Eagle .lbr, EasyEDA JSON, or ZIP library file was available to the current import tool.
Closest Flux library results were unrelated high-density Hirose mezzanine connectors and should not be used for COM-HPC Mini.
Missing-part requests were submitted for:
Samtec ASP-230333-03
Amphenol 10163479-14340T1LF
Version 4.0 Selection
User selected:
Samtec ASP-230336-03 — COM-HPC 400-position male carrier plug, 10 mm stack height, column termination.
Reason: use the taller 10 mm stack height for more clearance and cooling.
Flux library status: exact part was not found during library search. A missing-part request was submitted for Samtec ASP-230336-03. Footprint import/create from Samtec PDF/PADS resources is likely required before real placement.
5 mm stack height supports a lower-profile carrier/module assembly than 10 mm.
Samtec provides PDF print and PADS resources, which should help create/import a footprint if the Flux library part is unavailable.
Fallback / alternate:
Amphenol 10163479-14340T1LF — COM-HPC 400-position plug, 5 mm stack height.
This has been superseded by the Version 4.0 user selection of Samtec ASP-230336-03 with 10 mm stack height for more clearance and cooling.
Critical Open Questions
Do we need any alternate weld-tab / hold-down version for additional mechanical robustness, or is ASP-230336-03 acceptable as-is?
Should a second-source Amphenol 10 mm equivalent be kept as fallback?
Which exact COM-HPC Mini module will be used? The module vendor mechanical drawing may constrain connector stack height, keepout, and mounting-hole placement.
Can the user provide the PICMG COM-HPC Mini Carrier Design Guide or module vendor carrier-board design files if available?
Next Actions
Obtain/upload a usable EDA library package for Samtec ASP-230336-03: KiCad .kicad_sym + .kicad_mod, Altium .SchLib + .PcbLib, Eagle .lbr, EasyEDA JSON, or a ZIP containing these files. PDF/PADS references alone are not enough for the current automated import path.
Define COM-HPC Mini module mechanical keepout and mounting holes.
Confirm module-side connector compatibility and 10 mm stack clearance.
Only after those are locked, place the real connector footprint on the 105 mm x 115 mm Version 4.0 board outline.
